Of course, but what if they don't like the type mechanism and they prefer to 
rely upon the namespace in the XML instance? What happens if they want to 
rely upon the HTTP header to carry that information? What happens if the 
type KeyInfo object changes (a newer version with a tweaked namespace) and 
while they want the URIof the KeyInfo signed, they don't want its Type 
signed and consequently don't have the ability to change it? Since we aren't 
specifying any MANDATORY application behavior with respect to type, why 
REQUIRE the syntax?

I'm not wondering if it's easy to do, I'm wondering what requiring it
